Class BeanValidator

java.lang.Object

org.zkoss.bind.validator.AbstractValidator

org.zkoss.bind.validator.BeanValidator

All Implemented Interfaces:

Validator

Direct Known Subclasses:

BeanValidator

public class BeanValidator
extends AbstractValidator

A JSR 303 compatible validator for a property-binding.

Notice : Before use this validator, you have to configure your environment (depends on the implementation you chosen). Here is a article Integrate ZK with JSR 303: Bean Validation talks about how to set up JSR 303 in ZK with Hibernate implementation.

It validates a single property of a bean and sets the invalid message by AbstractValidator.addInvalidMessage(ValidationContext, String).

Since 8.5, you can assign a self-defined message key by appending a key parameter.

To use this class, you have to add @validator('beanValidator') or @validator('org.zkoss.bind.validator.BeanValidator') to the property-binding

Example

<grid width="600px">
   <textbox id="tb" value="@bind(vm.person.firstName) @validator('beanValidator')"/>
   <label value="@load(vmsgs[tb])"/> 
 </grid>
 

<grid width="600px">
   <textbox value="@bind(vm.person.firstName) @validator('beanValidator', key='fn')"/>
   <label value="@load(vmsgs['fn'])"/>
 </grid>
 

Note

It doesn't supports to validate a property of a form which properties are load from a bean, if you want to validate the form property of the bean, you could use org.zkoss.zkmax.bind.BeanValodator

Since:

6.0.0

Validate the value

Parameters:

clz - the class of bean

property - the property of bean

value - the value to be validated.

groups - the validation groups (since 8.0.0)

Returns:

the ConstraintViolation set.

Since:

6.0.1

validate

public void validate(ValidationContext ctx)

sort

protected void sort(java.util.List<javax.validation.ConstraintViolation<?>> viloations)

Sort the violations, make multiple violation order more predictable. By default, sort it by the constraint name.

Parameters:

viloations -

getValidationInfo

protected java.lang.Object[] getValidationInfo(ValidationContext ctx,
                                   java.lang.Object base,
                                   java.lang.String property)

Get the bean class of the base object and property to validate.
By default, it returns the class of base object directly.

Parameters:

ctx - the validation context

base - the base object

property - the property to validate

Returns:

a object array, the first item is the bean class of base object, 2nd item is the tuned property regards to the bean class

Parameters:

ctx -

violations -
